Abstract

The invention discloses components of a high-performance getter alloy. The high-performance getter alloy comprises the following components of, in parts by mass, 40-80 parts of zircon, 12-18 parts ofa material A and 0-6 parts of a material B; the material A comprises the following components of, in percentage by weight, 20%-30% of graphite, 5%-15% of vanadium, 1%-8% of niobium and the balance iron; and the material B comprises the following components of, in percentage by weight, 10%-20% of nickel, 6%-14% of chromium, 3%-12% of aluminum, 5%-15% of cobalt and the balance iron. The invention further discloses a processing method of the high-performance getter alloy. The air suction rate and the air suction capacity of the machined getter alloy are greatly improved, the air suction performance of the getter alloy is greatly improved, meanwhile, the activation temperature of the getter alloy is reduced, the cost is saved, and the purposes of energy conservation and consumption reduction are achieved.

Description

technical field [0001] The invention belongs to the technical field of getter materials, specifically a composition of a high-performance getter alloy, and also relates to a processing method of a high-performance getter alloy. Background technique [0002] Getter refers to the general term for preparations or devices that can effectively absorb certain (kinds) of gas molecules, and is used to obtain or maintain vacuum and purify gases. The getter has various forms such as powder, dish, ribbon, tube, ring, cup, etc. Getters are widely used in vacuum electronic devices, creating a good working environment for the device, stabilizing the characteristic parameters of the device, and having an important impact on the performance and service life of the device: increasing the vacuum degree of the vacuum device in a short time (up to 10 -4 Pa) to eliminate the residual and re-released gas after the device is exhausted and sealed off and during the aging process, which is benefic...
